摘　　要：为了实现对特定要求导电油墨配制的配前指导,建立了油墨等效电阻率与颜料颗粒半径、颗粒间距、颗粒与溶剂(连结料)电阻率等参数之间关系的理想随机数学物理模型。采用该模型对两种导电油墨进行了实验验证,模型预测结果与实验结果基本吻合。运用该模型研究了油墨颜料颗粒的精细程度及颜基比对导电油墨导电性能的影响,结果表明,颜料颗粒越精细、颜基比越小,等效电阻率越大。In order to realize a guidance for making electrocon-ductive printing ink, an ideal random mathematical-physical model is proposed and can be used to calculate the effective resistivity of printing ink. This model sets up the relationship between the effective resistivity of printing ink and the parameters of pigmental particle radius, particle distance, particle resistivity, solution resistivity and etc. The computing method has been proved to be true by experiments with two kinds of electroconductive printing ink. Our computing results are kind of agree with that experiments. By applicating the model, we have studied the influence of degrees of the pigmental particle＇s size, ratio between the volumes of pigmental particle and solution on the effective resistivity of electroconductive printing ink. The results show that the smaller pigmental particle radius and ratio of volume between the pigmental particle and solution are, the bigger effective resistivity is.
